Abstract: In a method of increasing the sensitivity of a photosensitive member (1a) for inputting digital light, the photosensitive member is prepared to have a steep variation in the value of γ of a latent image formed on the photosensitive member. Digital light (3) and another light (4) are applied to the photosensitive member (1a) at substantially the same time. The other light is emitted by an incandescent light (9), a LED or a fluorescent lamp. With this method, even when the input signal light is very weak, a clear picture image can be obtained.

Abstract: A method and an apparatus for forming elongated composite parts having constant cross sections. The apparatus comprises a form having a cross section, a portion of which is complementary to a first portion of the desired cross section of the elongated part. The apparatus further comprises a holding means (24) having a cross section, a portion of which is complementary to a second portion of the desired cross section of the elongated part. Plies (10) of preimpregnated composite material are held within a slip tape (12), which, in turn, is forced against the complementary cross section of the form by the holding means. The apparatus is then passed lengthwise along the slip tape enclosing the preimpregnated plies of composite material to cause the slip tape to tighten around the preimpregnated plies and to generate a slip tape-enclosed, elongated part which is appropriately shaped to pass through a pultrusion die.

Abstract: In the manufacture of an electronic device, e.g. an infrared detector of cadmium mercury telluride, a gas stream (36) comprising two or more reactants is passed over a heated substrate (29) in a reaction zone (C) of a reactor vessel (1) so as to deposit material in a layer (30) on the substrate (29). One reactant, e.g. a readily decomposible cadmium alkyl (Me₂Cd), is supplied to the reaction zone (C) by means of an injection tube (12) which passes through a heated first zone (A) of the vessel (1). The tube (12) has a narrow bore (y) to provide a high flow velocity for this reactant (Me₂Cd) through the first zone (A). In accordance with the invention, the tube (12) widens in at least one dimension (x), towards its outlet end, so as to provide a wider outlet for injecting the reactant (Me₂Cd) into the gas stream (38,36) with a lower flow velocity which matches more closely the flow velocity of the gas stream (38,36). A more balanced mixing is achieved leading to improved compositional homogeneity in the deposited layer (30), even for difficult materials such as cadmium mercury telluride. The heated first zone (A) may comprise a capsule (2) containing e.g. a pool of mercury (3), and such a capsule (2) preferably has an outlet (a) of smaller cross-sectional area within which the widened outlet of the injection tube (12) is concentrically arranged so that the gas stream (38) is symmetrically constricted around the outlet of the injection tube (12).

Abstract: A surface cleaner wherein abrasive particles are directed against a surface to be cleaned, after which the abrasive particles rebound into the cleaner and return for recirculation. Several features are involved. First there is provided an accelerator(180)for the normally gravity flowing abrasive particles to accelerate the particles towards a throwing wheel(90) wherein the abrasive particles are spread over a greater depth of an associated throwing vane. Some of the abrasive particles will not rebound entirely up into the machine for return to the abrasive particle supply chamber. Accordingly, there is provided a separate path(222,100, 104)for the weaker rebounding abrasive particles to return to the accelerator(180). The throwing wheel(90) includes a tubular hub(150)into which one of the supporting bearings (152) for the associated shaft (134) is telescoped. This permits throwing wheels of different widths to be utilized. The vanes (164) of the throwing wheel (90) are flat vanes having at their inner ends enlargements (178). The vanes slide through slots (160) with enlarged inner openings in an axial direction for mounting and removal. The vanes can be removed from the cleaner through an opening in one of the side walls thereof after a cover plate (120) has been removed. There is also a wear plate (212) which controls in part the direction of flow of abrasive particles from the throwing wheel (90). The wear plate (212) protects part of the housing and most particularly one of the housing seals with the surface being cleaned.

Abstract: A first surface of a first metal component of an ink jet print head is bonded to a second surface of a second metal component of the ink jet print head, the first and second surfaces being of materials having the same or similar coefficients of thermal expansion. A layer of filler material is electroplated or otherwise placed on at least one of these surfaces. The filler material has a melting point which is below the melting point of the first and second components, and the total thickness of the filler material on the surfaces together is in the range of from approximately one-sixteenth micron to approximately five microns, with one-eighth micron to two microns being a preferred range. These surfaces are placed together and subjected to heat and pressure to diffusion bond the surfaces without melting the filler material. The diffusion bonding is performed in one approach until no more than approximately one micron of filler material remains between the surfaces. Thereafter, the filler material is melted without melting the first and second components to thereby braze the first and second components together.

Abstract: The present invention provides melt-bondable, bicomponent fibers suitable for use in nonwoven articles, said fibers having as a first component a polymer capable of forming fibers and as a second component a compatible blend of polymers capable of adhering to the surface of the first component. The second component has a melting temperature at least 30°C below the melting temperature of the first component, but at least about 130°C. The blend of polymers of the second component comprises a compatible mixture of at least a partially crystalline polymer and an amorphous polymer. The fibers made according to this invention allow nonwoven webs prepared from these fibers to have a reduced level of shrinkage under conventional processing conditions. Accompanying this reduction in shrinkage is a reduction in curling or agglomerating of the individual bicomponent fibers, thereby providing a nonwoven web that will not mar smooth surfaces.
